【摘要】:三峽庫區(qū)蓄水后水文變化從以前的自然水文變成了庫區(qū)水文條件,而且隨著水文條件的改善,三峽大壩上游的通航能力也得到極大的提高。但伴隨著的也是碼頭的使用頻率增加、負荷增高使碼頭不斷的破損。因此碼頭檢測的重要性不斷增加,而目前碼頭檢測評估還稍落后于其他行業(yè)。本文主要以三峽庫區(qū)成庫后帶來的各種改變對高樁碼頭帶來的影響為依據(jù)。并根據(jù)高樁碼頭所處環(huán)境,以及結(jié)構(gòu)特點?偨Y(jié)三峽庫區(qū)碼頭病害,建立檢測技術(shù)指標體系。并從橋梁檢測中引入并適當修改了檢測技術(shù)標準,使碼頭檢測技術(shù)標準更詳實。本文研究以結(jié)構(gòu)可靠度為基礎(chǔ)理論,運用AHP層次分析中的專家調(diào)查法,對碼頭檢測、碼頭結(jié)構(gòu)設(shè)計,碼頭安全方面的教授進行調(diào)查問卷研究獲得權(quán)重系數(shù),然后借鑒并改動部分橋梁中的評分公式,使碼頭評價能有一個較為量化的數(shù)字指標,而不是以前的一個完全是定性的檢測結(jié)論。然后在定量的基礎(chǔ)上運用了模糊評價中F法的半梯度法將定量的分數(shù)轉(zhuǎn)為對碼頭健康的一個定性等級描述,研究三峽庫區(qū)高樁碼頭的健康檢測評價體系。最終形成一套操作性強、易理解的檢測體系。因此這樣的評價結(jié)果可以讓人對碼頭健康同時有定性的和定量的結(jié)果,更加易于理解碼頭整體健康等級,以及更易于了解碼頭的整體健康狀況。對三峽庫區(qū)高樁碼頭檢測評估的發(fā)展有著較大的幫助。
[Abstract]:The hydrological change of the three Gorges Reservoir has changed from the former natural hydrology to the reservoir hydrological condition, and with the improvement of the hydrological condition, the navigation capacity of the upstream of the three Gorges Dam has been greatly improved. But also accompanied by the increase in the frequency of wharf use, the increasing load of the wharf is constantly damaged. Therefore, the importance of wharf inspection is increasing, and the evaluation of wharf inspection is lagging behind other industries. This paper is mainly based on the influence of all kinds of changes brought by the three Gorges Reservoir area on the high pile wharf. And according to the environment of the high pile wharf, and the structural characteristics. This paper summarizes the wharf diseases in the three Gorges Reservoir area, and establishes a technical index system for detection. The technical standard of bridge detection is introduced and modified appropriately, which makes the technical standard of wharf detection more detailed. In this paper, based on the theory of structural reliability, using the expert investigation method in AHP hierarchy analysis, the weight coefficient is obtained by questionnaire research on wharf detection, wharf structure design and wharf safety. Then the scoring formula of some bridges is used for reference and modified so that the evaluation of wharf can have a more quantitative numerical index instead of the former one which is completely qualitative. On the basis of quantitative analysis, the semi-gradient method of F method in fuzzy evaluation is used to change the quantitative score into a qualitative description of wharf health, and the health detection and evaluation system of high pile wharf in the three Gorges reservoir area is studied. Finally, a set of operational, easy to understand detection system is formed. Therefore, the evaluation results can make people have both qualitative and quantitative results on the wharf health, make it easier to understand the overall health grade of the wharf and understand the overall health status of the wharf. It is of great help to the development of the inspection and evaluation of the high pile wharf in the three Gorges Reservoir area.
